So I recently purchased a new washer and immediately noticed some water hammer when the water fill valve shuts. After doing some research its quite common with new washers because the valves are so fast acting compared to washers from even 15 years ago. We only use the cold water so I closed the valve to the hot water supply and pinched back half way on the cold side. This did help but its still hammering more than I'd like.

 I ended up looking into solutions and found that an easy "remedy " is a water hammer arrestor. Basically a shock absorber that screws onto the back of your washer and onto the water supply hose. My questions are...does anybody have experience with these ? Do they work as advertised?  What is the life expectancy? Asking mainly in regards to the Sioux chief brand as that is what I've seen recommended most and also seems to be fairly priced and widely available.

When I was a plumbing apprentice back 20 years ago all we’d use was Sioux Chief. As far as life expectancy I can’t help with that. Hammer arrestors are code here.

 

 

 

 

Edit*  A quick google search shows the Sioux Chief brand will last around 500,000 cycles.

Thanks for the response. I ordered one, in fact I just received it. Ill install it when I have some time...I'm in the middle of a big plant shutdown and will likely work 70+ hours this week.
